I've had this car for a few years now, works perfectly until recently. This last month the turbo is quitting at around 2400rpm just does and I can't find a reason why. I have to say one of the injectors is bad but I'm waiting for a new one. I've had it inspected ,the turbo is fine the vacuum is good just can't figure out why.

 

The turbo cutting out at 2400 RPM is likely caused by the bad injector; replacing it should fix the issue.
